OIL BURNER.

Application filed August 23, 1923.

To aZZ whom it may concern:

Be it known that I, BENJAMIN H. Anniirs, a citizen of the United States,residing at Stephens, in the county of Ouachita and State of Arkansas,have invented a new and useful 'Oil Burner, of which the following is aspecification.

This invention aims to provide novel means whereby liquid fuel, such asoil may be heated preparatory to being burned, beneath a boiler or atany other place where combusition takes place, novel means beingsupplied for controlling the movement of the oil and for supplyingpressure to the oil.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in View, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in section, a device constructed in accordance with theinvention, parts remaining in elevation; Figure 2 is a section on theline 2-2 of Figure 1.

The device forming the subject matter of this application comprises ahollow body 1 including an outer wall 2 and heads 3 and 4, a tubularmember 5 extending between the heads 3 and 4 and being located withinthe outer wall 2. A heating chamber 6 exists between the tubular member5 and the outer wall 2 and a fuel tank 7 exists within the tubularmember 5. A steam inlet pipe 8 communicates with the upper portion ofthe heating chamber 6 and is mounted in the outer wall 2. The numeral 9marks a U-shaped steam outlet conduit, wherein a valve 10 is interposed,one end of the conduit 9 being mounted in the lower portion of the outerwall 2 and communicating with the heating chamber 6, the other end ofthe conduit extending beneath the body 1 and being connected to a casing12, preferably in the form of a coupling, that end of the conduit 9which is assembled with the casing 12 carrying a reduced nozzle 11located Serial No. 658,997.

within the casing. A. discharge pipe 1 1 for the fuel is connected tothe casing 12 and is located in axial alinement with the nozzle 11. Acombined air inlet and fuel pipe 15 extends through the heads 3 and 4;and through the tank 7, the lower end of the pipe 15 communicating withthe casing or coupling 12. Within the fuel tank, the pipe 15 is suppliedwith a lower opening 16 and with an upper opening 17. The fuel isdelivered into the tank 7 through a pipe 18 mounted in the head 1 andcommunicating with a passage 19 in the head, the passage 19 discharginginto the tank 7.

In practical operation, steam passes through the pipe 8 and enters theheating chamber 6, the steam leaving the heating chamber 6 through theconduit 9, under the goverance of the valve 10 the steam traversing thenozzle 11. The oil enters the pipe 18 and the passage 19 and moves intothe tank 7, where the oil is heated. The oil enters the pipe 15 throughthe opening 16 and any gas which may have accumulated on top of the oilenters the pipe 15 through the opening 17. The steam proceeding throughthe nozzle 11, creates a suction in the pipe 15 and the air and fuel aredrawn through the pipe 15 into the casing or coupling 11, the fuelproceeding through the discharge pipe 14, to the place of use.

The device is so constructed that the fuel will be heated, and the steamwhich is used for heating purposes is used, also, to advance the liquidfuel after the same has been heated.

What is claimed is:

1. In a device of the class described, a hollow body comprising a fueltank and a heating chamber disposed thereabout, means for introducingsteam 'into the heating chamber, means for introducing fuel into thefuel tank, a casing having an outlet, a conduit leading from the heatingchamber to the casing, a nozzle communicating with the conduit anddischarging into the casing, anda combined air and fuel pipe, open atone end, the pipe passing through the tank and communicating at itsopposite end with the casing, the pipe having an opening establishingcommunication with the tank.

2. In a device of the class described, a body comprising a fuel tank anda heating chamber disposed thereabout the tank and the chamber havingcommon edges, means for introducing steam into the heating chamber atone end of the heating chamber, means for introducing fuel into the fueltank at the opposite end of the heating chamber, a casing located. atone end of the body and having an outlet, a U-shaped con duit leadingfrom the heating chamber and communicating with the casing, a Valveunder the control of an operator and interposed in the conduit, a nozzlecommunicat ing With the conduit and discharging into the casing, and acombined air and fuel pipe, open at one end, the pipe passing throughthe tank and communicating at its opposite end With the casing, the pipehaving open-- 15 ings communicating with the tanln' the openings beingspaced apart, longitudiinally of the pipe, and one opening being locatedclosely adjacent to that one of the heads Which is remote from thenozzle.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
